The invention relates to crude oil and to the ignition device, cartridge or msert element adapted to be inserted intothe,

cylinder which automatically ignites at the compression temperatures "set upin thecold cylinder in turning overthe engine and then continues to burn until the engine is' running. The known devices of this type consist of ordinary gun cotton or gu'n cotton treated to with camphor. The ignition temperatures of such devices however, are either so high that they only ignite with difliculty in small capacity cy ders-or elselgmtlon takes place so rapidly that the tinder or other :5 carrier is'not ignited by it. j Much improved conditions are obtained when the ignition of the device accordance with the present invention, is :fac1litated'by an easily i 'ted phosphorou 0 1111101111 80 which is applied to the de 'ce in anysu table manner; I v I The invention. is more pari zicularly de- 1 scribed :with r ference to the accompanylng drawing presenting a longitudlnal sect ona 26 view ofrthe device. The insert element a in form of a-cartridge d of an adhesive.

consists of a match orjpaper' unpregnat 1 with saltpetre. 'To th at end of the cartridge which projects hen insertedmt'o the-cylinder, is applied by adhesive means a phosphorou's compound 72, such as 7 phosphorous sesqui-sulphide; the ignition temperature of which is in the neighbourhood of100" C.

In order to' protect ternal influences before use, it is preferable to completely enclose at least V vided'with the .easily' igm V compound,'by. means. of a paper acket c whichis preferably opene sertion of the device in thexcylindeni 7 Instead of applying the phosphorus com-- pound to the insert element a by V means,'the cartridge may be completely or partially saturated. with a solution of a phos .phoru'scompound g 7 It will beappreciated that m an internal combustion engine operated with the ignition device as described the charge in the cold cylinder need only be compressed to raise it:

A jcartridge'adapted to be inserted in the combustion cham er"'-for starting crude oil engines and containing a combustible element adapted by its, combustion to provide heat of sufficient intensity and duration to start the normal ignition process and a phosphorus compound 'ignitable by the heat of air compression in sald'combustion chamber at a temperature'below the ignitionpointof the-oil,"
